SEPARABLE CONNECTER Application led August-6, 1931. Serial No. 555,440.`

rIhis invention relates to conduitsv composed of separable members orsections, and particularly to conduits used with motor ve'- hicles tosup-ply parts of such vehicles with conditioning means such as oil,grease, air,

etc., although the invention may be otherwise used.

A separable connecter constituting the preferred embodimentJ of theinvention includes members which are separable, by a sidewse movement ofone member relative to the other, the members being adapted to bequickly and conveniently connected and separated without being rotated.

` My improved connecter comprises a headed member, and a socketed'memberwhose socket is complemental to the head of the headed member, andadapted to be engaged with said head by a sidewise movement of Vthesocketed member relative to t-he headed member, the engagement of thesocket with .the head preventing swinging movement of leither memberrelative to the other.

The headed member includes a head 13, having a longitudinally extendingsubstantially flat external side face 13a, containing a port which maybe surrounded by an internal valve seat 15. Said member includes a shank12 having a passage 14a communicating with a passage 14 in the head, thevalve seat 15 being in one end of said' passage.

The passage 14 may contain a valve17 normally closed on the seat 15 by aspring 18.

:thus .ensured when tively connected'.

The socketed member of the connecter includes a socket 23 complementalto `the head The said members arerelati'vely movable to cause the sockettok receive thehead and register its port with the head po'rt'andthereby operatively connect the members. I. pro- (.625 vide stop Ameansfor arresting the .relative movement in one direction when said portsregister with each other, said means ,permitting the separation of themembers. i

The socket'is formed to closely embrace the head and maintain the wipingface 20 in vclose` contact with the port-containing side face so .thateach face automatically wipes the other, rand removes accumulations offoreign matter, such as dirt and grease, therefrom whenv the members arebeing-connected, a close joint between said faces being the members areoperarlhe outer face of thevalve 17 is Hush with the end `face 13a sothat said faces are simulp taneously wiped.

l preferably embody the above mentioned stop means in a shoulder 13b onthehead 13. adapted to limit the movement of the socket onto the head13, and thereby ensure registration of the socketed member port with thehead port, so that when the members are operatively connected' materialis permitted to flow from one member into and through they other. y

In the preferred embodiment of the invention shown by Figures 1, 2, 3,and 4, the socketed member includes an internally threaded outer tube 19on which the socket 23 is formed, the threaded bore of said tube openingon the flat end wall 2()I of the socket, an externally threaded innertube 21, longitudinally adjustable by rotation in the outer tube 19, anda central tube 22 secured in andv 100 longitudinally adjustable with theinner tube. The central tube 22 has a flange or shoulder 25, bearing onone end of the inner tube 21, and an end portion containing slots i '.5122a constituting the port of the socketed member. When the tubes 21 and22 are retracted', as shown by Figure 3, the central tube 22 and itsoutlet ports are withdrawn from the socket, so that the latter isadapted to receive the head 13. l/Vhen the tubes 21 and 22 are projectedas shown by Figure 4, the outlet end of the central tube 22 bears on andopens the valve 17, the ports 22a being within the passage 14, as shownby Figure 4.

The adjustable inner tube 21 is provided with an annular compressiblepacking washer 24, bearing on the flange or shoulder 25 and compressiblebetween said shoulder and `the end face 13a of the head 13, to-preventleakage between said end `face .andl the wiping face 2O of the socket,said faces being rigid 'and incompressible.

f The socketed member may be securedin spring 47. The valve is formed ona valve rbody 45a which is cut away at one or more sides to provide apassage 48 Figure 5a for any suitable way to a hose 26, "constitutingthe flexible main portion yof a conduit communicating with a source ofsupply, and provided, if desired, with a valve (not shown) whereby itkmay be closed. l

Y Figure' 5 shows an embodiment of the invention suitable for use as astraight coupling, the members being in line with each other whenconnected, and adapted for use 'in connecting two lengths of hose.

1n this embodiment the headed member includes a head 41, having asubstantially flat end face 42 in which is a passage 43. An in- Vternalvalve seat 44 surrounds a port in the end`v face 42. A valve 45 movablein the Vpassage 43 and in the bore ofthe shank 46 of the headed member,is normally closed by a fluid passing through the connecter.

The socketed member includesa body por- "tion 49, and a socketcomplemental to the f duced portion on which is fitted an annular'VVhead 41 and adapted to be engaged with the head by a sidewise movementof the socketed member. The socket is formed on one end of the body 49and has an end wall 51 formed to abut the end face 42.

yThe socketed member includes also an inner tube or terminal 52externally threaded and engaged with an internal thread in the body 49.

The forward end of the tube 52 has a recupv washer 53 having a centralopening 547 constituting a port which registers with the bore of thetube 52 andl communicates with the port surrounded by the valveseat 44.

Fixed inthe forward end of the tube 52 and projecting therefrom, is ateat 55 which is arranged to bear on and open the valve 45 when the tube52v is adjusted to the position shown by Figure 6. This adjustmentcauses the tube 52 to compress the central portion of the washer 53against the end face 42 ofv the head, so that leakage is preventedbetween the faces 42 and 51; Movement of thesocket 50 onto the head 41is, in this instance, limited by the closed end 56a of'a slot 56 (Figure5)V formed in the socket, said closed end abutting the shank portion 46of the headed member,

so that the ports of thetwo members arev caused to register with eachother, when the l members are operatively connected.

It will be seen that the inner tube 21 shown 4by Figures 1, 3 and 4serves as an annular Y presser adapted to back the annular washer 24with its outer side flush with the internal end wall of the socketedmember as shownI by Figure 3,when the membersfare disconnected, so thatthe washer does not protrude into the socket and therefore does notoppose the con-v nection of theA members, said presser Y'being adaptedto compress the washer aft-er the connection of the members topreventleak- Y age' between the said head lend face and socket wall. c Il Y' It will also be'seen that the tube 52shown by Figure 6 also servesas an annular presser adapted to function like the inner tube21. i

It will be seen that the automaticwiping Si.) i

only to prevent leakage of materialbetween' the contacting facesA ofYsaid members, but also to clamp the opposite side faces of the headedmember against an internal face of the connected members, for example",by an from the position shown by ,Figure'4and by a fromtheposition shownby Figure 5. Said` pressing means may include the inner tube .21'(Figure 4),- or the inner tube 52 (Figure 5) each of said inner tubesbeing provided `the socketed member to opposeseparationcfllo' vupwardmovementof the'socketed member l' downward movement of the socketedmember A with a terminal such as the -outer endV of the ,Y

inner tube 22 (Figure 4) or the projecting teat (Figure 5). Saidterminal extends into thev annular washer, and is adapted to enter theport of the headed member and not stop positively preventing theseparation of' the connected members as indicated by Figures 4 and 5. Iclaim:
